I'm not seeing it, Cathy. The exterior photos of the Patriot don't show a roof AC and the second interior photo shows the traditional front mount installation. The only 16' pictures I could find are here, and the third exterior photo clearly shows a front mount AC through the open door. The options list for the 16' model also indicates front mount AC.

They're all 17'ers. They are Casita's bread and butter. They sell very few of the smaller units.

I found "front AC" listed in the options for the 16'er, but, oddly, not the 13'er. Pretty sure it's an omission. It's also interesting that the AC picture in the Patriot gallery is mounted under the front sofa, a layout that has been discontinued. Just shows that Casita is too busy making trailers to keep the website up-to-date.

You can identify a 17' model by the flat door, larger sliding rear window, single-level floor platform front to back, and a more pronounced trolley riser in the roofline. And, I still believe, roof-mounted AC.

Thanks, Jon. That has been helpful. I prefer A/C not on top. Totally personal preference and not a deal breaker. I like the 16' but you don't see them used very often. I am still pondering my options. None are perfect but I want to get as close as possible to my idea of "perfect".
